lights: Two all round red lights in a vertical line with a white light above overall
Dayshape: three balls in a vertical line
Maneuvering Signals (International): 1 short blast? 2 short blasts? 3 short blasts?
1 short blast: “I AM altering my course to starboard”
2 short blasts: “I AM altering my course to port
3 short blasts: “I AM operating astern propulsion”
Remember: PESO for inter.
Is acknowledgement of maneuvering signals needed in open waters?
No
Maneuvering Signals (Inland): 1 short blast? 2 short blasts? 3 short blasts?
1: “I INTEND to leave you on my port side
2: “I INTEND to leave you on my starboard side”
3: “I am operating astern propulsion”
Upon hearing 1 or 2 signal, other vessel shall acknowledge using same signal
Overtaking Signals (international): 2 prolonged, 1 short? 2 prolonged, 2 short?
2,1: “I intend to overtake you on your starboard side”
2,2: “I intend to overtake you on your port side
What is job of vessel about to be overtaken, upon hearing overtaking signals in international waters?
Acknowledge intention with 1 prolonged, 1 short, 1 prolonged, 1 short
Overtaking signals (inland): 1 short blast? 2 short blast?
1: “I intend to overtake you on your starboard side”
2: “I intend to overtake you on your port side”
PESO used in overtaking inland
What is job of vessel being overtaken upon hearing 1 or 2 blast signal? (inland)
Respond using same signal
When power-drive vessel are leaving a dock or berth, what shall they sound?
1 prolonged blast
When approaching an obscured bend or area of a channel (inland or int.) what shall they sound?
1 prolonged blast
What is danger signal in inland and international waters?
5 short blasts
(restricted visibility) Power driven vessels making way in restricted visibility shall sound what?
1 prolonged blast at an interval not to exceed 2 minutes
(restricted visibility) Power-driven vessel underway but not making way shall sound what?
2 prolonged blasts at an interval not to exceed 2 minutes
(restricted visibility) What vessels sound 1 prolonged and 2 short blasts in restricted visibility, at intervals not to exceed 2 minutes?
Not Under Command
